新素材·GoMars模型 You know that dust storms(沙尘暴) happen on the Earth. But do you know they can happen on Mars too? Now, Chinese scientists have a powerful new tool called the GoMars model. It can simulate(模拟) the dust cycle on the Red Planet just like a computer.
According to Xinhua News, Mars is like the Earth's close "sister" planet. Studying it could tell us about how life began, and one day, it might even become a future home for human beings. However, we still don't know much about the weather on Mars, especially its dust cycle. This cycle is very complicated(复杂的) because it is about the dust, the thin air, and the wind on the ground all working together. Big dust storms can cover the sky, making it hard for rovers(探测器) to work and making challenges for future space tasks.
The GoMars model first came out in 2023. It's very powerful because it can simulate the movement of not just dust, but also water and carbon dioxide($\ce{CO_{2}}$) on Mars. In a new study, scientists used it to study how dust moves over a very long time—more than 100 years. The model also made an interesting discovery: dust activity on Mars is the strongest between 12 p.m. and 1 p.m. local time.
This research is very important. It helps scientists understand real-time weather on Mars, almost like having a weather forecast(预报) for another planet. In the future, when taikonauts land on Mars, this knowledge will help them pick safer times and places to explore, getting us ready to learn more about our "red neighbour".

答案
B
【语篇解读】本文是一篇说明文。文章主要介绍了中国科学家研发的GoMars模型。它可以模拟火星上的尘埃循环，帮助人类更好地了解火星天气，为未来的火星探测任务提供支持。
1. C 【解析】写作手法题。根据文章开头“But do you know they can happen on Mars too?”可知，作者通过提问的方式开启了这篇文章。故选C。
2. D 【解析】细节理解题。根据第三段“It's very powerful because it can simulate the movement of not just dust, but also water and carbon dioxide ($\ce{CO_{2}}$) on Mars.”可知，GoMars模型可以模拟火星上尘埃、水和二氧化碳的运动。故选D。
＞＞直接理解题
3. B 【解析】补全文章题。前文提到“我们对火星的天气，尤其是尘埃循环知之甚少，这给未来的太空任务带来了挑战”，后文则引出了GoMars这一强大工具。因此，此处应填入一个承上启下的句子，说明我们需要好的工具来研究它们。故选B。
4. B 【解析】细节理解题。根据第三段“dust activity on Mars is the strongest between 12 p.m. and 1 p.m. local time”可知，火星上的尘埃活动在当地时间中午12点到下午1点最为强烈。故选B。
